First off, my goal is only to reduce the understeer present with the car in stock form.
2013 WRX 5-Door Premium - all stock suspension
During the winter, I noticed the car wanted to push rather than oversteer on snow. I'm thinking upgrading the rear sway bar to maybe 19mm would get me close to neutral.
Was hoping someone could either confirm this would do it, or offer suggestions. I'm assuming I'd want new endlinks if replacing the swaybar.
My car is just a daily driver, but I HATE understeer. I'd much rather have a slight oversteer tendency rather than a push. I'm also running Michelin Pilot Sport A/S 3 all season tires, so I really don't want to go to a stiffer front bar if just a small increase in the rear would do it.
